 Association
The service used to establish access point/station(AP/STA) mapping and enable STA
invocation of the distribution system services(DSSs).
 Authentication
The service used to establish the identify of one station as a member of the set of stations
authorized to associate with another station.
 Channel
an instance of medium use for the purpose of passing protocol data units(PDUs) that may be
used simultaneously, in the same volume of space, with other instances of medium use(no
other channels) by other instances of the same physical layer(PHY), with an acceptably low
frame error ratio due to mutual interference. Some PHYs provide only one channel, whereas
others provide multiple channels. Examples of channel types are shown in the following tables
Single channel n-channel
Narrowband radio-frequency(RF) channel Frequency division multiplexed channels
Baseband infrared Direct sequence spread spectrum(DSSS) with
code division multiple access
 Wired equivalent privacy(WEP)
The optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to provide
data confidentiality that is subjectively equivalent to the confidentiality of a wired local area
network(LAN) medium that does not employ cryptographic techniques to enhance privacy.
